In your experience with regular seeds, what percentage did you have with females over males?

Yall speaking with a lot of certainty about something that is less settled than you probably imagine. At least as recently as the 2017 edition of the Cannabis Grow Bible there's still lots of speculation as to whether environment leads to different sexes. Also there's often a natural difference in the sexes, there's not exactly 50% males and 50% females in human population, for example. Also just from a functional level, one male can pollinate many females. The ideal situation would not be 50/50

Last regular seed grow. 8 plants. 3 females.

My average was 60% male. No matter the seed count. Always more male then female.

Over an infinite number of samples any problem with only two solutions has an exact 50/50 distribution of results. Sex is encoded in the seeds DNA. No article you fimd on the internet or YouTube video can change that fact, sex is independent of environment.

Tell that to reptiles. Temperature determines sex in crocodilians, sea turtles, and tuataras iirc.

Cannabis sativa L. is a dioecious species with sexual dimorphism occurring in a late stage of plant development. Sex is determined by heteromorphic chromosomes (X and Y): male is the heterogametic sex (XY) and female is the homogametic one (XX). The sexual phenotype of Cannabis often shows some flexibility leading to the differentiation of hermaphrodite flowers or bisexual inflorescences (monoecious phenotype). Sex is considered an important trait for hemp genetic improvement; therefore, the study of the mechanism of sexual differentiation is of paramount interest in hemp research. A morphological and molecular study of Cannabis sativa sexual differentiation has been carried out in the Italian dioecious cultivar Fibranova. Microscopic analysis of male and female apices revealed that their reproductive commitment may occur as soon as the leaves of the fourth node emerge; the genetic expression of male and female apices at this stage has been compared by cDNA-AFLP. A rapid method for the early sex discrimination has been developed, based on the PCR amplification of a male-specific SCAR marker directly from a tissue fragment. Five of the several cDNA-AFLP polymorphic fragments identified have been confirmed to be differentially expressed in male and female apices at the fourth node. Cloning and sequencing revealed that they belong to nine different mRNAs that were all induced in the female apices at this stage. Four out of them showed a high degree of similarity with known sequences: a putative permease, a SMT3-like protein, a putative kinesin and a RAC-GTP binding protein.

Let me dig up the section from the Cannabis Grow Bible about sex expression. I believe the anecdotal observation was that better conditions led to more females.

That makes sense. The pH of a woman's body can help decide the sex kind of. Something like a lower pH will be more favorable to male sperm than female sperm. So you have a better chance to have a boy if her pH is lower.

Some history for ya. The term Honeymoon came from old times. It was called that because the wife would drink honey mead for a moon cycle after the ceremony, which is almost a month. This supposedly helped their chance to have a boy, and I think there's been study's since then, but don't have any links.

Of course plants are different though and don't have sperm, lol.
